The Ubuntu team has released Dapper Drake Flight CD4, the 4th alpha release on the way to the final release of Dapper Drake (which is now in upstream version freeze). Besides many cosmetic changes to the boot sequence, GDM, and GNOME in general, this release features Espresso (a live-CD installer), GNOME 2.14 Beta 2, and much more. The team has also included a 'very special and early gift' - Novell's Xgl and Compiz. Downloads for Ubuntu, Kubuntu, and Edubuntu are in the release announcement.
